ISB ELL' DRIVE FOR UNIT PRESSES AN D FOLDERS OriginalFiled Marcfi 16, 1926 awn/wags Patented May 9, 1933 UNITED STATES PATENTOFFICE JOHN A, ISBELL, OF PLAIN FIELD, NEW JERSEY, ASSIGNOR TO WOODNEWSPAPER MACHINERY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OFVIRGINIA DRIVE FOR UNIT PBESSES AND FOLDERS Original application filedMarch 16, 1926, Serial No. 95,036. Divided. and this application filedNovember 21, 1929, Serial No. 408,711.

This invention is a division of my application Serial No. 95,086, filedMarch 16, 1926, on a drive for unit press and folder.

The principal object of this invention is to provide a compact drive forconnecting the several units of a press with the main driving means insuch a way that the several units can be disconnected from the driveindividually so as not to interfere with the driving of the other unitsand in which this can be done in a convenient manner.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which Fig. 1 is aplan of a certain typeof multiple press showing the drive for theseveral units arranged in accordance with this invention, and

Fig. 2 is a side view thereof.

Heretofore one method employed for connecting up several units consistedof a direct connection between the ends of the shafts of the cylindersin each unit, generally constructed with projections on the shafts whichengaged each other to drive the several units together. In that case thedisability of one of the intermediate units breaks the powertransmissions to any unit, which may be driven from it on either sidethereof, and throws out the whole mechanism until the necessary repairsare made.

This invention is designed for the purpose of obviating this difliculty.

In the form shown, the two press units C and D are set up side by side,that is, with the corresponding cylinders parallel with each otherlongitudinally. Of course, the invent-ion is not limited to theemployment of two units only. Furthermore the folder F is located at theend of the series.

A motor 20 drives a main driving shaft 21 through the usual gearing.Three separate chain drives 22, 2'3 and 24 are employed to deliver powerfrom this single shaft adjacent to the motor to the printing units C andD and the molding mechanism F. The main shaft 21 and the driving shafts26 of the press units and the driving shaft 25 of the folder areparallel.

Renewed March 31, 1932.

In thisway the driving shafts of the units 0, D andF are driven fronithedriving shaft 21 at whatever speed may be desired. Ordinarily,'o fcourse, these driving shafts are all driven at the same speed. By thismeans any intermediate .unitmay be silenced by disconnecting thecorresponding sprocket chain from the sprocket wheels, without in anyway interfering with the operation of the driving or folding units oneither side of it.

The supply rolls 27, it will be noted, can be located out of the waydirectly under the press units.

It is to be understood that although I have shown only two printingunits the invention is not limited to any particular number. Thisarrangement secures all the objects mentioned above, without in any waydecreasing the output of the press or limiting the operation of itsseveral units.

Although I have illustrated and described only one form of the invention1 am aware of the fact that modifications can be made in the way ofconnecting the parts which have been described with the units of thepress and with the motor. Therefore, I do not wish to be limited in thisrespect but what I do claim is 1. In a printing machine, the combinationwith a plurality of printing units arranged adjacent to each other, sideby side and a folding unit arranged at the end of the series, of a mainshaft, means for driving the main shaft, a series of sprocket wheels onthe main shaft, a series of sprocket wheels, one on each of the drivingshafts of the several units, and sprocket chains connecting the sprocketwheels with each other in pairs side by side.

2. In a printing machine, the combination with a plurality of printingunits arranged adjacent to each other, side by side, and

folding unit arranged at the end of the series, of a main shaft, anddriving shafts for the printing and folding unit-s, all parallel witheach other, means for driving the main shaft, a series of sprocketwheels on the main shaft, a series of sprocket wheels, one on each ofthe driving shafts of the several units, and sprocket chains connectingthe sprocket wheels with each other.

3. In a printing machine, the combination with a plurality of printingunits arranged adjacent to each other, side by side, and a folding unitarranged at the end of the series, of a main shaft, means for drivingthe main shaft, a serles of sprocket wheels on the main shaft, aseriesof s rocket wheels,

me on each of the driving sha ts of the several units, and sprocketchains connecting the sprocket wheels with each other in pairs side byside and supply rolls for the press units located below them. f

4. In a printing press, the combination with printing units and foldersarranged side by side, of a drive shaft parallel to the printingcylinders of said units, and individual chain connections from the driveshaft to each unit and the folders.

In testimony whereof I havehereunto affixed my signature.

JOHN A. ISBELL.
